METHOD AND SYSTEM FOR COMMUNICATION BETWEEN A MANAGEMENT-SERVER AND REMOTE HOST SYSTEMS

摘要

The current document is directed to methods and systems for exchange of information between management servers and remote host systems managed by the management server. In disclosed implementations, a local proxy server associated with the management server and a remote proxy server associated with the remote host systems both locally store configuration data for the host systems and exchange configuration differences through a wide area network in order to synchronize the stored configuration data between the proxy servers. Requests generated by the management server for host configuration data are satisfied by the local proxy server and configuration-data synchronization efficiently employs exchanges of configuration-data differences, rather than repeated transmission of all or large portions of the configuration data.

1. A logical communications bridge comprising:
a local proxy server that includes one or more processors, one or more memories, and a communications agent that exchanges messages with a management server through a first local area network and that exchanges messages through a wide area network with a remote proxy server; the remote proxy server that includes one or more processors, one or more memories, a communications agent that exchanges messages with one or more remote host systems through a second local area network and that exchanges messages through a wide area network with the local proxy server; and bridge adapters in the local proxy server and the remote proxy server that each locally stores configuration data for the one or more remote host systems, the remote bridge adapter in the remote proxy server periodically, for each of the one or more remote host systems
obtaining configuration data for the remote host system,computing a configuration differential that encodes differences between the obtained configuration data for the remote host system and the configuration data locally stored by the remote bridge adapter for the remote host system, andtransmitting the configuration differential to the local proxy server, the local proxy server using the configuration differential to update the configuration data locally stored by the local proxy server for the remote host system.
